I'll check my FSM for the self check. I do not have consult, if that is required.
I should have mentioned compressor is not functioning, due to low refrigerant. I guess I hoped that I should be able to get ambient temperature vent air, without compressor, it always seems warmer than outdoor air.
I'm pretty sure compressor has slow leak, I see a drop or two of flourescent green oil on bottom side, near pulley, I think it's time to replace compressor again: I did replace compressor, TXV, drier, o rings about 10 years ago, leak only developed recently. I normally buy all AC parts from Arizona Mobile Air, but am open to other source of quality components. Thanks for the assistance.
